Question

即使应用程序空闲或处于后台，我们如何才能在 phonegap android 应用程序中获得 GCM 推送通知。

＆＃34; katzer /科尔多瓦-插件背景模式＆＃34;似乎不起作用......

＆＃34; 我在应用运行前景时成功获得推送通知＆＃34;

cordova版本：4.3.0 android 4.4 phonegap 4.2.0

我将复制下面的通知功能...... 在 deviceready

上

function onDeviceReady（）{

        try 
            {
                      pushNotification = window.plugins.pushNotification;
              jQuery("#app-status-ul").append('<li>registering ' + device.platform + '</li>');
                      if (device.platform == 'android' || device.platform == 'Android' ||
                                device.platform == 'amazon-fireos' ) {
            pushNotification.register(successHandler, errorHandler, {"senderID":"my-project-id","ecb":"onNotification"});   
              } else {
                          pushNotification.register(tokenHandler, errorHandler, {"badge":"true","sound":"true","alert":"true","ecb":"onNotificationAPN"});  // required!
                      }
            }
        catch(err) 
            { 
              txt="There was an error on this page.\n\n"; 
              txt+="Error description: " + err.message + "\n\n"; 
              alert(txt); 
            } 
        }

和

function onNotification（e）{

            switch( e.event )
            {
                case 'registered':


      if ( e.regid!='' )
      {

           android_reg_id =  e.regid;


          jQuery.ajax({
            type:"POST",
            url:SITEURL+"index.php?r=Manageuser/App_Reg_Android",
            data:{regid: android_reg_id,employeeno:employeeno}
        }).done(function(msg) {

        });             

      }
                break;                    
                case 'message':
                  // if this flag is set, this notification happened while we were in the foreground.
                  // you might want to play a sound to get the user's attention, throw up a dialog, etc.
                  if (e.foreground)
                  {                      
               //jQuery("#app-status-ul").html('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');
                // on Android soundname is outside the payload. 
                      // On Amazon FireOS all custom attributes are contained within payload
                      var soundfile = e.soundname || e.payload.sound;
                      // if the notification contains a soundname, play it.
                      // playing a sound also requires the org.apache.cordova.media plugin
                      var my_media = new Media("/www/"+ soundfile);

                      my_media.play();
                   }
        else
        {


               if (e.coldstart)
                    $("#app-status-ul").append('<li>--COLDSTART NOTIFICATION--' + '</li>');
               else
                    $("#app-status-ul").append('<li>--BACKGROUND NOTIFICATION--' + '</li>'); 
                    //location.href = e.payload.redid;
        // otherwise we were launched because the user touched a notification in the notification tray.

        }

          jQuery("#app-status-ul").html('<li>MESSAGE -> MSG: ' + e.payload.message + '</li>');        
        //window.localStorage.setItem("push_que", e.payload.redid);
        //location.href = e.payload.redid;

        break;

                case 'error':
        jQuery("#app-status-ul").append('<li>ERROR -> MSG:' + e.msg + '</li>');
                break;

                default:
        jQuery("#app-status-ul").append('<li>EVENT -> Unknown, an event was received and we do not know what it is</li>');
                break;
            }
        }

使用的插件是com.phonegap.plugins.PushPlugin 2.4.0＆＃34; PushPlugin＆＃34;

Answer 1

我不确定您使用哪个插件来捕获推送通知，但我建议您使用phonegap-build/PushPlugin。它有一个处理程序，可以在应用程序打开时，在后台或关闭时捕获通知。如果您按下通知，它将打开您的应用程序。

要使用该插件，只需将其放入您的代码中：

var pushNotification;

document.addEventListener("deviceready", function(){
    pushNotification = window.plugins.pushNotification;
    if ( device.platform == 'android' || device.platform == 'Android' ){
        pushNotification.register(
        successHandler,
        errorHandler,
        {
            "senderID":"replace_with_sender_id",
            "ecb":"onNotification"
        });
    }
    //the rest of your deviceReady function
});

// result contains any message sent from the plugin call
function successHandler (result) {
    alert('result = ' + result);
}

// result contains any error description text returned from the plugin call
function errorHandler (error) {
    alert('error = ' + error);
}

现在我们已经将插件的实例设置为全局变量pushNotification以及使用GCM服务注册Android设备的if语句，但是您需要在此处放置Google API项目的senderID：{ {1}}。如果设备已成功注册，它将调用函数"senderID":"replace_with_sender_id"。该功能应该是这样的：

onNotification

此函数接收来自GCM服务的事件，该事件告诉它该做什么。如果设备已注册，则会在控制台中记录设备注册ID，如果收到消息，则会检查应用程序是否在后台打开，关闭或打开，并会提醒消息function onNotification(e) { console.log('event received: '+e.event); switch( e.event ) { case 'registered': if ( e.regid.length > 0 ) { //Here you should call a function that sends the registration-ID //to your server so you can save it and send push notifications to your device console.log("regID = " + e.regid); } break; case 'message': if ( e.foreground ) { //App was open when the notification was received console.log('foreground'); // on Android soundname is outside the payload. var soundfile = e.soundname || e.payload.sound; // if the notification contains a soundname, play it. var my_media = new Media("/android_asset/www/"+ soundfile); my_media.play(); } else { if ( e.coldstart ) { //App was closed console.log('coldstart'); } else { //App was open in the background console.log('background'); } } alert('message: '+e.payload.message); break; case 'error': alert('GCM error: '+e.msg); break; default: alert('An unknown event has occurred'); break; } }。

由于您使用的是Android，我刚刚收到了Android的代码。我希望这就是你要找的东西。

接收推送通知不要求应用在后台运行。

Cordova Push Plugin
我推荐这个插件： https://github.com/phonegap-build/PushPlugin 用于接收推送通知（当应用未运行时）。
该页面上的文档非常好该插件支持iOS，Android和其他平台。

服务器端选项
我不知道你在服务器上运行的是什么，它实际上听起来不像你在服务器端有任何问题，但是为了提供更完整（更通用）的cordova推解决方案答案，我想提一下：
对于Android GCM推送消息，请查看https://www.npmjs.com/package/node-gcm
对于iOS APN推送消息，有https://github.com/argon/node-apn
我已经包含了这些链接，因为即使您没有在服务器上运行节点，这些页面上的文档也是一个很好的起点，它们都有更多非常有用的信息链接。

上面推荐的插件已被弃用，替换插件 https://github.com/phonegap/phonegap-plugin-push 具有更简单的界面。
这个客户端代码的简单示例包含大多数用例所需的一切：https://github.com/phonegap/phonegap-plugin-push/blob/master/docs/EXAMPLES.md

当应用程序处于空闲状态或处于后台时，如何获取cordova android推送通知？
